Descrição geral

Zinc is an inexpensive, readily available versatile reagent in organic reactions and is commonly used as a reducing agent in organic synthesis. Zinc dust is used to reduce carbonyls, carbon-halide bonds, carbon-oxygen bonds, alkynes, and heteroatom bonds such as N-N and N-O bonds. It is also used to prepare various organozinc reagents. [1] Additionally, Zinc has been used in several well-known named reactions, like the Reformatsky reaction, the Knorr pyrrole synthesis, the Serini reaction, and the Simmons-Smith cyclopropanation.

Aplicação

Reducing agent; used for preparation of organozinc reagents, Reformatsky reagents, and the Simmons-Smith reagent (cyclopropanation).

Zinc is also used as a:

  • Reductant in the hydrothermal CO2 reduction to formic acid in batch reactors.
  • Catalyst in the synthesis of propargylamines by one pot, three component coupling of aldehydes, amines and alkynes in acetonitrile.[2]

Questions

1–2 of 2 Questions  
  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
